This particular Demiurg is the project of nomadic Swedish musician Rogga Johansson who is known for his work in Paganizer, Deranged and Edge Of Sanity. The band was formed in 2006 and soon featured Dan Swanö on drums, Ed Warby also on drums a little later, Johan Berglund on bass and others as guests.

Sensing a winner, the Dutch label Mascot Records made a return to death metal realms and signed the act. Guido, formerly of Hammerheart and Karmageddon, now worked at Mascot Records and initiated the signing. The group’s debut appeared in early 2007. It was produced by Swanö at his Unisound Studio. Demiurg would release its third album, Slakthus Gamleby, on July 30th, 2010 through Cyclone Empire Records.

Reviews

DEMIURG - BREATH OF THE DEMIURG - MASCOT
Demiurg is a death metal band built upon a foundation of old school genuine Swedeath. The band could have obtained a higher mark than seventy, but it does not for one obvious reason.
Demiurg is the project of Paganizer and Ribspreader man Rogga Johansson who has also worked with Deranged and Edge Of Sanity. Aside from impeccable credentials, Rogga has recruited Dan Swanö - who has since departed however - for this little project of his and put together a solid album consisting of ten tracks and forty minutes of music. The vocals are deep and convincing, the guitars distorted and compose great riffs reminiscent of the heady days of 1989 to 1991. Bands like Edge Of Sanity, Bolt Thrower, Carnage and early Death could well be reference points for this outfit. The drums of Dan Swanö, in contrast, are a tad too mechanical and dry sounding. Songs like Flesh Festival and Monolithany pack enough elegant brutality to rise above the norm were it not for the aforementioned caveat. The problem is the odd keyboard flare-up. Like a bad case of cold sore upon an impeccable face the death metal is watered down by the faint sound of keyboards which have a knack for popping up at the most inopportune time - not that there is any good time for pop instrumentation in metal. Breath Of The Demiurg loses a swig or two as a result. The song Orbiting A Dead Sun is a good example of the offence and titled as a result appropriately.
Demiurg is worth recommending and full of good brutal madness, but one cannot help ask why the keyboards were added and how much better things would have been without them. - Ali “The Metallian”

DEMIURG - THE HATE CHAMBER - MASCOT
Demiurg, for me, is a band that came out of nowhere a year ago suddenly keying in reliable death metal. The Hate Chamber is more of the good stuff, except two specific qualifications need to be noted.
At its core this is an album full of great death metal that is genuinely heavy, brutal and even catchy at times. The vocals are deep and gargling blood. With speed creeping into pounds of pounding death metal and the band utilizing a dense production for the guitars it all seems more than all right, except Demiurg has another aspect to it as well. Chief among these is the occasional tendency to use a My Dying Bride riff. The occasional use of background keyboards and clean vocals is also of point-deducting concern.
Right off the bat, Resurrecting The Rotting (Flesh Festival Pt.II) not only delivers alliteration but also a shot of brutality but with keyboards. This element is repeated on other songs like The Convulse Meridian and Cult Of Dagon. This last song is the album’s worst with its lame clean singing and Queensrÿche rhythm. The Apocalyptic though has the doomy riff, but packs a lot of action into the song. The vocals are screechy like hell. Cremated Lies The Dead has a fun/heavy solo that is too short. Opus Morbidity (City Of IB PT.III) has those nifty pounding beats. The song starts with an intro before crashing into death metal speed headfirst. Material like this gives Demiurg the momentum on the death metal scene. - Anna Tergel
